JOHN LAXTON, OF TORONTO, ONTARIO, CANADA.

GAS-=STOVE.

SPECIFICATION forming part of Letters Patent No. 390,377, dated October2, 1888.

Application filed October 20, 1887. Serial No. 252,910.

Be it known that I, JOHN LAXTON, of the city of Toronto, in the countyof York, in the Province of Ontario, Canada, have invented.

certain new and useful Improvements in Gas- Stoves, (for which I haveobtained a patent in Canada, No. 26,837, dated June 3, 1887,) of whichthe following is a specification.

The object of the invention is to design a stove in which the heat fromthe gas-jets shall be utilized to the fullest extent; and it consists inthe peculiar combinations and the novel construction, arrangement, andadaptation of parts, the whole being constructed substantially ashereinafter more particularly eX- plained.

Figure 1 is a vertical section through a I) of Fig. 2, with parts of theinner plate, 0, broken away. Fig. 2 is a vertical section through c d ofFig.1. Fig. 3 is a sectional plan through c f of Fig. l.

A represents the upper oven, and B the lower oven. These ovens areseparated by the cast-metal plate C, on the bottom of which is fixed thecorrugated deflecting-plate D. The sides of the ovens A B are made oflight sheet metal ,and are surrounded on their three sides by a jacket,E, made of light sheet metal, and between which and the sides of theovens A and B an air-space, L, is left, as indicated. A cast-metal base,F, is provided, and a top, G, of similar material.

As I claim nothing peculiar in thepot-holcs or manner of heating them,they do not appear in the drawings.

Perforated pipes II arelocated in the bottom of the oven 15, and aperforated pipe, I, is located near the top of the oven B, imme diatelybelow the deflectingplate D. These pipes H and I are suitably connectedto the gasmain, and are provided with such cocks as may be necessary toproperly regulate the supply of gas to be admitted into them. On eitherside of the oven A, I form, within the jacket E, passage-ways J, leadingfrom the top of the oven 13 to a point near the top of the oven A. Theheat created by the burning gas which escapes through the perforationsin the pipes H and I is conveyed through the pas- (No model.) Patentedin Canada June 3, 1887, No. 26,837.

sage-ways J into the chamber J, from which it finally escapes throughthe pipe K. By th s arrangement the heat from the burning gas 1S fullyutilized.

\Vithin the space L at the rear of the stove I arrange a coil ofwater-pipes, M, through which water is caused to circulate in the usualmanner. At the bottom of the space L, I place a perforated pipe, N,which is supplied with gas in the same manner as the pipes H and I. Whenthe gas escaping from the pipe N is lighted; the heat within the space Lis very intense. Consequently the water passing through the pipes M issoon heated.

In practice I do not find that it is neces sary to keep the gas from thepipe N constantly lighted, as the heat which radiates from the sides ofthe ovens A and B is sufficient to keep the water in the pipes Mmoderately hot. In order that the air in the space surrounding the ovensA and B may be kept in circulation, I perforate the sides of thepassage-ways J, and in order to increase the ra diating surface in thespace L,I place on either side of the pipes M the corrugateddeflectingplates 0.

What I clain as my invention is 1. The combination, with the oven A, ofthe oven B, the plate C, separating said ovens and preventingcommunication therebetween, the perforated gaspipe in the oven 13 inprox- 'imity to said plate, and the passage-ways J,

connecting the top of the oven B with the top of the oven A,the jacketE, and the gasjet arranged in the space between said jacket and the ovenB, and the coil M above said gasjet, substantially as described.

2. The ovens A and B, connected together by the passage-ways J, incombination with the plate 0, separating said ovens, the perfo ratedgas-pipe below said plate, and the deflecting-plate D, located at thetop of the oven B in proximity to said perforated gas-pipe,substantially as and for the purpose specified.

The ovens A B and the plates C separating them, combined with thepassage-ways J, connecting said ovens, the perforated pipes H, arrangedaround the bottom of the oven B, and the perforated pipe I, arrangednear the top of said oven, and both connected Withasuit- D, attached tothe bottom of said plate 0 able source of supply, substantially as andfor above the pipe I, substantially as described.
